Checking the Configurations
After BFD is enabled on both ends of a link, run the display isis [ process-id | vpn-instance
vpn-instance-name ] bfd session { all | peer ip-address | interface interface-type interface-
number } command. The command output shows that BFD status is up.

The system view is displayed.
To disable the BFD function on an interface, run the isis bfd block command in the
interface view to disable the interface from establishing BFD sessions.
Enable dynamic BFD on an IPv4 interface.
1. Run:
system-view
The system view is displayed.
2. Run:
bfd
BFD is enabled globally.
3. Run:
quit
The system view is displayed.
4. Run:
interface interface-type interface-number
The interface view is displayed.
5. Run:
isis bfd enable
BFD is enabled on the interface.
After BFD is configured globally and the neighbor status is Up (on a broadcast
network, DIS is in the Up state), default BFD parameters will be used to establish
BFD sessions on the specified interface.
6. (Optional) Run:
isis bfd { min-rx-interval receive-interval | min-tx-interval transmit-
interval | detect-multiplier multiplier-value | frr-binding }
Run this command when BFD session parameters need to be configured for a specified
interface.
NOTE
The priority of BFD configured on an interface is higher than that of BFD configured for a
process. If BFD session parameters are configured for both a process and an interface, the
parameters on the interface will be used to establish a dynamic BFD session.
